Notes. The columns from left to right give the values of the cosmic matter density, Ω_m, the linear root-mean-square fluctuations smoothed on the 8 h⁻¹ Mpc scale, σ₈, and the redshift-independent equation of state, w. In all models the baryon density is set to Ω_b = 0.04356, the density of the relativistic species to Ω_r ≃ 0.00008, the curvature to Ω_k = 0, the reduced Hubble constant to h = 0.72, and the slope of the primordial spectrum to n_S = 0.963.
